Sandra Bullock on Jesse James' Cheating, Divorce: "Nobody Can Be Prepared for Anything"

Sandra Bullock is in a much calmer place than she was about three and a half years ago. In March 2010 -- fresh off of her Best Actress Oscar win for Blind Side -- the actress, now 49, saw her five-year marriage to Jesse James absolutely implode in front of the public. Motorcycle customizer James, 44, infamously cheated on his movie star wife with multiple women, many of whom spoke to the press about the affairs.

"We're all where we're supposed to be," Bullock says in the October issue of Vogue when asked about that painful ordeal. "I am exactly where I want to be now. You can't go backward. I'm not going backward. I'm grateful that I'm here, blessed to have what I have. Nobody can be prepared for anything."

Indeed. the Gravity star has much to be thankful for these days: Back in early 2010, shortly before James' cheating -- and their June divorce -- dominated headlines, Bullock had secretly adopted son Louis. "If you end up in a place where you can look back and go, 'It happened, but I'm so lucky to be sitting where I am sitting.'" muses Bullock.

The Southerner chuckles to Vogue about how she managed to keep Louis under wraps for so long, even as she hit the 2010 awards circuit, winning one trophy after the next for Blind Side. The brunette says she would often give phone interviews to journalists with baby Louis gurgling in the background . "Thank God for the mute button," she says.

Although the Proposal star had wanted to adopt for some time, Louis arrived with not much warning, with a quick call from an adoption agency. Instantly ecstatic, Bullock resisted the urge to break the news at the 2010 Oscars. "I wanted to get up there and say, 'Guess what?!'" but she opted not to.

While Bullock's career is better than ever -- The Heat was one of summer 2013's biggest hits, and Gravity is getting major Oscar buzz -- the still-single actress knows what her priorities are. "Work was my life before . . . Now I have no reason to leave home."

Are more kids in the future? Maybe. "If all of a sudden someone said, 'You have five more kids,' I’d be totally OK with it," she says. "I'm having such an amazing time. Whatever comes our way, we handle as a family. It's not just me anymore."
